Apple Watch Bands Sizing

Hi everyone , i am facing some problems on choosing the right apple watch , hope you guys can help me out .

I'm going to buy an Stainless Steel apple watch (42mm) . Now my problem is if the band ( leather loop M and Milanese Loop ) can fit my wrist . I use a measuring tape to measure my wrist , it was 140mm when tighten up hardly and 150mm when normal wrap . I printed out a Apple Watch paper mockup 42mm leather loop and milanese loop ( the mockup apple watch screen is legit and right , i compared to the real one using my apple store app, but i don't know if the band lengths is right ) , and the mockup fit my band perfectly . As apple website written leather loop and milanese loop need atleast 150mm wrist to fit , so i'm really worry it will be loose on my skinny wrist ( which is 140mm if measuring tape tighten up hardly ) . Please help me guys , and one got the length of the Leather Loop ( M ) and Milanese Loop , i want the length , please guys me guys =) .🙂

* i'm not going to get the 38mm for some reasons and i can't visit my local apple store as well =( .

ANY LEATHER LOOP AND MILANESE LOOP OWNERS HERE ? I NEED THE LENGHT OF THEM ( NOT FITTING SIZE ) , thanks !!!!
